Plugin BetterGrim

BetterGrim, enhanced Minecraft server anticheat

BetterGrim is an open source anticheat plugin for Minecraft Java Edition, created as a fork of Grim AntiCheat. It adds extra detection checks while refining existing ones to improve protection against movement, combat, and other unfair advantages. Built for server side use, it follows Grim’s predictive movement simulation approach and supports asynchronous, multithreaded processing, helping maintain accurate checks with limited performance impact.

It is designed for Bukkit, Paper, Spigot, Purpur, Folia, and Fabric environments, with broad version coverage and Java 17 support. BetterGrim is archived, but its feature complete code remains useful for administrators evaluating protection options. At BoxToPlay, we recommend it for owners seeking a technical anticheat foundation for their Minecraft server.
